openspec-apply

Load openspec-apply after OpenSpec approval, then execute each task listed in tasks.md sequentially without additions or skips. The Skill loads test-tdd for verification, runs each implementation step, and validates results against prescribed tests before committing changes.

Test-driven implementation means each code task integrates test-tdd verification: you write or modify code, run the prescribed test commands immediately, and confirm the results pass before moving to the next task. This ensures changes match the approved specification exactly.

No. The Skill enforces phase-driven execution and prohibits task additions or skips. You must follow the exact sequence and specifications in tasks.md to maintain the integrity of the approved change and ensure all verification steps pass.

The Skill documents each completed task and reports next steps. Implementation is complete when all pending tasks in tasks.md execute successfully and test-tdd verification commands confirm the results match the approved specification.

When test-tdd verification fails, the Skill halts execution and reports the failure without proceeding. You must resolve the failed task against the approved specification before continuing to maintain exact compliance with the OpenSpec change.
